DFB Quantum Cascade Lasers(pulsed QCL): 6000 nm - 14000 nm
nanoplus Distributed Feedback Lasers (DFB) are speciﬁcally designed for high-precisiongas detection using tunable diode laser absorption spectroscopy (TDLAS). Our devices
operate reliably in more than 50,000 installations worldwide. For 25 years nanoplus has
set the standard for DFB laser technology and is the only manufacturer
routinely providing DFB lasers at any wavelength.

Any custom wavelength is possible: You tell
us what you need and we deliver it. With ourpatented DFB technology we design any
wavelength between 760 nm and 14 μm.

Our excellent spectral purity is characterized
by a large side mode suppression ratio(SMSR) of > 35 dB, giving your system a lowsignal to noise ratio against crossinterference.

A narrow linewidth below 3 MHz guarantees ultra-precise scanning of the absorption linefeature. The high output power of several mW yields a stronger signal and increases yourmeasurement precision.
Fast and wide wavelengthtuning is required for in situ
systems. Most customers use ascan rate of 10 kHz and beneﬁt
from our very large tuning
coeﬃcient.

”Do not change your ideas, let us delivera laser that ﬁts your application.”

We oﬀer various packaging options, e.g. several freespace housings including TEC and NTC, ﬁber coupling,collimation and custom designs. What do you require?
If you require custom speciﬁcations, please contact us.
Nearly 80 % of our devices are more or less customerspeciﬁc. As nanoplus is a fully vertically integrated
company, we control the entire process chain from design
to packaging.
Both nanoplus production facilities are based in Germany.
To guarantee consistent product quality we apply a strict
and ISO certiﬁed quality management system at alllevels.
Our sales and R&D teams have long-standing experience in developing lasers.
They will advise you in your design and realization phase as well as after-sales:
We make market leaders!
